The present invention relates to punching mechanism for perforating cards in a predetermined manner, and relates more particularly to a control for the automatic return of the carriage by which the punch set-u is made. In machines of the character to w iich this invention relates there is a traveling carriage equipped with a sin le row of setting pins corresponding in num er and alinement to one row of punches and to a corresponding row on the card to be punched and the construction is such that the carriage moves step by step across the punches in response to the manual operation of keys by which the pins are selected. When all of the pins are set to produce the predetermined arrangement of punches to perforate the particular card, a key is operated so that, with the card in register, means will function to cause the card to be perforated by the punch set-up, and thereafter the punch set-up must be eliminated, the carriage returned to its initial position, and the set-up pins restored ready for a new setup to accord with statistics or data to be reproduced in the form of perforations upon another card. The present invention is concerned more particularly with the automatic return of the carriage so that this movement takes place timed relation to thepunching and restoring o erations.

Some of the-"o jects of the present invention are to provide an improved automatic carriage return mechanism for card punching or perforating machines; to provide means operating automatically to return the carriage of a punching machine at a predetermined time in the cycle of operations; to provide means for timing a punch carriage return to take place after the punch set-up reset device has been set to function; and to provide other improvements as will hereinafter appear.

In the accompanying drawings Fig. 1 represents-a fragmental elevation in part section of a punching machine to which the present invention is applicable; Fig. 2 is a diagrammatic perspective of those parts of the machine embodied in the invention. Fig. 3 is a fragmentary, detail, top plan view, illustrating the clutch between the main driving shaft and the shaft of the punching machine,-to-

gether with the arm or device by which the clutch is controlled; the clutch bein shown engaged in this view. Fig. 4 is a lfixe view of the same, showing the clutch disengaged b the action of the cam on the head of the clutc pm.

Referring to the drawings, one form of the present invention is shown as a plied to a machlne for punching holes 1n cards in a predetermined arrangement so that each card becomes a perforated record of certain statistics, business transactions, or other data. The machine 10 is shown merely as a representative type to which the invention relates, and a detailed explanation of its parts and operation may be hadby reference to Letters Patent No. 1,305,557. Generally stated, such a punching machine consists of a set-up mechanism comprising settlng or settable pins 11 which are vertically movable and respectively in alinement with punches 12 supported by a guide plate 13 over the card registration passage 14 and over the vertically movable die 15 which is perforated in a manner to correspond to the punch arrangement. The punches 12 are thus caused to enter the perforations in the die 15 when the latter is reciprocated with no card in the passage 14, but when a card 1s 1n the passage a reciprocation of the die 15 will carry the card upward to thus push back all punches free to move, that is, unset punches, While the set punches are held and forced through the card to give the selected perforated arrangement. The selection and setting of the pins 11 take place by means of selecting pins 16 mounted in a carriage 17 which moves step by step across the setting pins 11 under control of an escapement mechanism to be hereinafter described and which is operated by the operating keys which control the action of the selecting pins 16. As in my prior patented construction each setting pin or bar 11 is provided with a cam a arranged beneath a notch therein, and each bar 11 moves in a cut-out in a horizontally mo vable locking bar I), one such locking bar being provided for each row of setting pins or bars 11. Each locking bar is forced by a spring a to the left, as the parts appear in Fig. 1. 'It will be understood, therefore, that as each setting pin or bar 11 is forced down to effective position, it will be automatically locked by the associated locking bar 6 in its lowered position to hold the companion punch against upward shifting movement.

In order to bring about a restoration of all of the setting pins 11 after the punching operation has taken place, each locking bar 6 extends to the left beyond the frame of the machine, (as the parts appear in Fig. 1), and such projecting end of each locking bar coacts with a separate releasing lever d. A'socalled erasing device in the nature of a roller e is carried by an arm f pivoted at g to the carriage 17. Normally this roller is out of cooperative relation with the levers d but may be brought into cooperation therewith an cause the engaged locking bars 6 to be successively shifted to the right (as the parts appear in Fig. 1), thereby releasing the locked setting pins 11 and enabling them under the force of their springs k to be returned upward to nonefi'ective position. In the machine of my hereinbefore mentioned patent the erasing device including the roller e is hand controlled and operable at will. It is one of the objects of my present invention to provide in addition automatically operating means by which said erasing device is actuated in timed relation to the punching operation and after such operation has been effected, and also in timed relation to the return of the carriage and before said carriage is automatically picked up and returned to initial position, as will hereinafter more clearly appear. This effects automatically a result previously effected by hand. The carriage 17 is propelled by a tension coil spring 18 so that it travels step-by-step under control of the escapement mechanism in the manner of a typewriter carriage and each rest space brings the one row of selecting pins 16 in superposed alinement with a row of setting pins 11. The cscapement mechanism disclosed in part herein is the same as that shown and described in my prior patent hereinbefore referred to and comprises an escapement wheel 2' carried by the carriage 17 and having a pinion j on the shaft of said wheel. Said pinion 7' meshes with a rack 70 fixed to one of the fixed rails Z on which the carriage travels. Feed dogs indicated generally at m coact with the escapement wheel to afford a step-by-step advance of the carriage. These feed dogs are actuated in the usual manner at each actuation of a selecting pin 16 to advance the carriage one step. A keyboard 20 is provided having keys 21, one for each selecting pin 16, arranged when depressed to cause a selecting pin 16 to be operated to make a set-up of the corresponding pin 11 by transmitting the movement of the key through a flexible wire 22 to mechanically operate the selected pin and on the return stroke of said key advance the carriage 17 one step, though variations of this construction may be made whereby a single key sets up more than one pin 11. Other keys are provided for other control purposes, such for example as to cause desired carriage space or carriage skip movements to operate the trip mechanism for actuating the punching machine and any other purpose.

The pin set-up is followed by the punching operation and as soon as the card is perforated the parts are reset and returned automatically for making a set-up for the next car It may be pointed out that the arm f of the erasing or resetting device is under control of a lever 27 carried by the carriage, and that a movement of said lever in one direction or the other controls the movement of the roller e into or out of cooperative relation with the resetting levers d. In accordance with my present invention I provide on said lever 27 a trip finger 26 located in the path of movement of a tri member 29 having a cam 28, the inclined face or edge of which cam coacts with the finger 26. The trip 29 is fixed to a reset block 30 which also carries a lug 31 adapted to coact with a projection 32 on the carriage 17 in order to pick up and transmit a'return movement to the carriage, but not until the cam 28 has first functioned to set the erasing or reset roller e in effective position. Thus, the construction and relation of the parts are such thatduring a travel of the reset block to the left in Fig. 2 the cam 28 will first engage the finger 26 and set the roller 6 to function. This takes place before the lug 31 reaches the projection 32 and therefore before any return movement is transmitted to the carriage 17. The erasing device having first been set in efl'ective position as indicated, the carriage will then be picked up and returned causing the roller 0 to coact successively with the lovers (I, thereby releasing the locking bars I) and permitting the locked pins 11 to return to their normal, ineffective positions under the action of their springs It. The reset block 30 is returned to its normal position by a coil spring 33 which maintains a tension thereon at all times.

For returning the carriage 17 to its starting position the block 30 is mounted upon a suitable fixed base 34 for sliding movement and is guided by a bar 35 upon which it is free to slide. The end of the block 30, opposite to the connection for the spring is connected by a flexible wire, cord or the like 36 to a winding drum 37 rotatably carried by a shaft 40 which receives motion periodically from a shaft 41 by way of bevel gears 42. The winding drum 37 is frictionally mounted upon the shaft 40 in such a manner that it will rotate with the shaft under all normal moms? tension, but in case the carriage return mecha-.

nism should get out of adjustment the drum will then automatically be released from the shaft to prevent damage or breaking of the cord or tape 36. The shaft 41 is provided with a clutch sleeve 43 which is free to rotate relative to the shaft 41 but transmits motion thereto only when engaged bythe driving clutch sleeve 44 which is keyed to the shaft 41 for sliding movement axially thereof, and this clutch connection is made whenever it is desired to return the carriage 17 to its starting position.

For actuating the movable clutch sleeve 44 it is circumferentially slotted to receive the bifurcated end of an arm 45 which is fixed to a rock shaft 46 while a spring 47 is under tension to pull the sleeve 44 to clutching en- I member at fixed thereon.

gagement. The rock shaft 46 has an arm 50 fast thereon for pivotal connection with a lock bar 51 which is provided with a recess 52 to receive a locking latch 53 'whereby in looking position the clutch arm 45 is held out of clutching position on the tension of the spring 47. The latch 53 is pivoted to a fixed pin 54 and is of bell crank form for connection at its nonlatching end with an operating core member 55 and is arranged to be returned to latching position by a spring 56 connected to a fixed part.

In order to transmit motion to the loose clutch sleeve 43, a sprocket and chain drive 57, 58 and 59 is provided and receives continuous motion from a main driving shaft 61 suitably geared to a motor driven shaft 62 or other power means.

This main driving shaft 61 is also arranged to transmit motion to the alined driven shaft 63 of the punching machine at the time a perforating or other operation is to take lace, as determined, in the present lnstance,

y a manual control. In order to effect such punching operation the shaft 63 has a cam Said cam member has a cam groove therein to receive an antifriction roller 0 carried near one end and at one side of a lever p pivoted intermediate its ends to the frame of the machine. The inner end of said lever is operatively connected to depending arms on the die 15 so as to elevate the latter at each punching I operation and then lower the die after the punching operation in order to free the punches from the card and permit it to be fed forward into a receiver by the usual card controlling means including the feed rollers Q driven from a gear on the shaft 63, at the same timebri'nging another card into place to be punched, as disclosed in my hereinbefore mentioned patent. It is necessary that the raising and lowering of the die take place before the carriage 17 is automatically returned and in timed relation therewith, which results are brought about by the means to be hereinafter described. The shaft 61 carof which a in 65 forms t e clutch enga 'ng element. he pin 65 is mounted for sli ing movement in a sleeve 66 whichis shaped to provide a seat for one end of a coiled spring 67, the other end of which presses against a collar 68 of the pin 65 to thus normally tend to project the pin 65 to clutching relation with the clutch 64. The pin 65 is normally held from being projected to effective position by a pivoted control arm 70 acting against a head 71 on the pin 65. The sleeve 66 is carried by an arm 72 fast to the driven shaft 63, so that each time the clutch pin 65 is projected to enga e the clutch disc 64 motion will be transmltted from the shaft 61 to the shaft 63.

For controlling the arm 70, a spring 73 and push rod 74 are provided, the former being interposed between the arm 70 and a fixed part to be under such tension as will normally hold the pin 65 out of clutching engagement, whereas the rod 74 is slidably guided in a bracket 75 and located to be shifted by a core 76 of a solenoid 77 to overcome the tens1on of the spring 73 to release the pin 65 at the proper time. The solenoid 77 is in a circuit of which the terminals 80 and 81 connect to a source of current, and the closing of which circuit is controlled by a con tactor key 82 of the usual spring type for bringing the normally spaced contactor 83 and contact 84 together. Thus the closing of,

the circuit energizes the solenoid 77 so that lts core 76 impels the push rod 74in a direction to move the arm 7 0 away from the head 71 whereby the pin 65 is free to slide, under the actlon of the spring 67 into clutching relatlon with the clutch 64. In consequence the shaft 63 is rotated with the shaft 61 but only makes one rotation because the arm 70 has been returned automatically by the spring 73 as soon as the solenoid is deenergized and the cam 85 of said arm 70 engages the head 71 as shown in Fig. 3, to withdraw the pin 65, from the clutch member 64 by a camming action during the last portion of the rotation of the shaft 63, as indicated in Fig. 4.

For the purpose of bringing about the carrlage return the terminals 80 and 81 are connected to a circuit including a solenoid and circuit closer comprising two brushes 91 and 92 so mounted as to rest upon a commutator 93 of insulating material having a conduct- 1ng strip 94 arranged to close the circuit through the brushes 91 and 92 in a certain position of the commutator. The commutator 93 is fast upon the main shaft 63 and angularly considered the circuit closing strip 94 is normally located so that the shaft 63 has completed the major portion of a rotation before the circuit is closed between the two brushes 91 and,92. This is to insure a completion of the perforating operation before any carriage return movement takes place. When the solenoid is ener ized its core 55 moves in a direction to withdraw the latch 53 from the recess 52 so that the lock bar 51 is released and the spring 47 then brings the movable clutch part 44 into clutching relation with the driven part 43 to transmit motion to the shafts 41 and 40 in order to wind the drum 37 so that the block 30 is actuated to return the carriage 17.

Provision is made for resetting the lock bar 51 at the end of the return movement of the carriage 17, and in the present instance this reset mechanism consists of a trip arm having a trip 96 located in the path of the block 30 near the end of its stroke. The trip arm 95 is fast to a shaft 97 suitably journalled for rocking movement and carrying an arm 98 which is connected to the lock bar 51. Thus when the carriage 17 reaches the end of its return stroke, the block 30 picks upthe trip 96 and thereby rocks the shaft 97 in a direction to cause the arm 98 to shift the bar 51 back to the position where it is automatically locked by the latch 53. This movement of bar 51 is communicated to the rock shaft 46 whose arm 45 opens the clutch.

In case it is desired to return the carriage 17 without causing the perforating mechanism to function a contactor key 100 is operated. This key is provided and arranged to control a contactor 101 and a contact 102 which are connected by conductors 103 and 104 in shunt relation to the brushes 91 and 92. This forms an auxiliary manually operable means for closing the circuit of the solenoid 90 so that the carriage return can be effected at will without actuating the arm 70 and while therefore the shaft 63 which controls the punching operation remains at rest.

From the foregoing it will be apparent that a complete unitary mechanism has been provided for returning the carriage of an analyzing or selecting unit of a card perforating machine to its initial or starting position, such return taking place either automatically at the end of a punch set-up step and punching operation and in timed relation to the latter or at will from any position in its travel. In the one case the return takes place automatically by the actuation of the punching mechanism, and in the other case the return takes place independently of any punching operation. By the present invention the operator of the punching machine has one less operation to perform because the same operating key that controls the punching step also brings about the carriage return, and it is no longer necessary for the operator to press the punch control key and then return the carriage by hand.

Briefly stated the operation of the machine is as follows:

A card having been fed in the usual manner into the passage 14 and into pro er position beneath the punches 12 and t e carriage 17 being in its initial position with the machine at rest the operator will proceed as follows:

A successive manipulation of the keys 21 in the key board will be made in accordance with the set-up to be effected. Each actuation of a key 21 will result in actuating the corresponding selecting pin 16 to move the companion pm 11 down to and lock it in effective position against the associated punch 12. The same operation of the key 21 through the actuation of a universal bar (not shown) results in actuating the escapement mechanism to advance the carriage 17 one step and bring the pins 16 into register with the next row of pins 11 and so on until a complete set-up of the punch controlling pins 11 has been effected.

The operator then depresses the key 82 and this results in shifting the arm 70 and establishing through the members 64 and 65, an operative driving connection between the constantly driven shaft 61 and the shaft 63. The turning of the shaft 63 during less than one rotation results in turning the cam n and operating the lever 10 to elevate the die 15 and effect a punching'operation and in then lowering the die to clear the punches from the card and permit a feed of the card to the receiver and the feed of a new card into place. After this punchin operation has been effected a further rotation of the shaft 63 brings the conducting strip 94 beneath the brushes 91, 92 closing the circuit which results in actuating the member 55 of the solenoid 90 to release the latch 53. The spring 47 then becomes effective to close the clutch 44, 43 and turn the winding drum 37 due to its connection thus effected with the constantly turning shaft 61. The turning of the drum 37 in the manner described moves the reset block 30 and causes the cam 28 thereon to first engage the finger 26, thereby moving the erasing device or roller 0 to effective position. After this has been effected the contact 31 on the reset block reaches the projection 32 on the carriage 17 and causes said carriage to be returned to its starting position. Just before it reaches such position the carriage coacts with the trip 96 (which was advanced when the locking bar 51 was released) and turns the rock shaft 97 to move the locking bar back to normal position, where it is engaged by the locking member 53, as shown in Fig. 2. The automatic shifting of the rock shaft 97 in the manner described results in shifting the clutch member 44 to releasing position and disconnecting the winding drum 37 from the shaft 61, so that the carriage comes to rest. .In the meantime ressureon' the key 82 has been released by t ie-operator and the force of the spring 73 has returned the arm 70 to normal position. When, therefore, the

head 71 of the clutch pin reached the cam 85' on said arm at the last portion of the rotation of the shaft 63, the pin 65 was cammed to released position, shown in Fig. 4 and thus disconnected the clutch members 64, 65 so that the shaft- 63 has come to rest after making one rotation. v

t should be understood that the setting of the erasing device 6, by the cam 28 before the carriage is picked up by theiesetting block 30, results in holding said resetting device in effective position during the automatic return of the carriage'in timed relationship with the punching operation and after the punched record in the card has been effected. It follows therefore that'dur ing such return movement of the carriage the erasing device e will act successivellyi on the levers d and will release the loc ing bars 6 from locked position, enabling all of the pins 11 to return to normal ine'fiective position. It will be seen therefore that the operation of the erasing device a vis automatically effected in timed relationship with the punching operation and after the punched record in the card has been effected.

While but one form is shown in which this invention may be embodied, it is to be understood that the invention is not limited to any specific construction, but might be applied to various forms without departlng from the spirit of the invention or the scope of the appended claims.
